Abstract: A jointing metal fitting for joining wooden members in buildings is formed of a metal fitting main body having a U-shaped cross section, a securing device for securing the metal fitting main body to a first wooden member, and an axial securing device for securing a second wooden member to the metal fitting main body. The metal fitting main body includes a plate-like back section to be secured to the first wooden member, a plate-like holder section to be secured to the second wooden member, and a plate-like side section for linking the side of the back section and the side of the holder section. An axial securing groove is formed in the holder section to have an upper part opened to an upper end of the holder section. The first and second wooden members can be firmly and easily joined by the metal fitting.
